Ada 95 grammar for aflex?

["Ralf Reißing" <reissing@informatik.uni-stuttgart.de>]

I'd like to make lexical analysis of Ada 95 code, 
so I am looking for an Ada 95 grammar for aflex. 

All I found so far was a lex grammar mentioned in the FAQ, e.g. at
ftp://ajpo.sei.cmu.edu/public/ada9x/rm9x/lexer9x.l, but the file
can not be found on the server anymore.

Alternatively I'd be interested in an Ada package that does the
job of a lexical analyser which splits an Ada file into a token
stream. I've taken a look at the lexical analyser of gnat, but it
seems to be quite complex and heavily coupled to other gnat
packages.

TIA,
	Ralf
